Application led December 9, 1912. Serial No. 736,202.

lt has for its particular object the produclti-on of a nozzle in whichthe two jets of oil or fluid will be forced into the path of each other,thereby causing the two streams to cylindrical body portion of thenozzle has av be broken into a fan shaped spray.

The invention consists in certain novel` vof the present invention. Fig.2 represents a transverse section of a portion of said pipe and a nozzlesecured thereto. Fig. 3 represents a longitudinal section of the same,and Fig. 4 represents an end view of said nozzle. Similar charactersdesignate like parts throughout the several igures of the drawings.

'In the drawing, 10 represents the usual delivery pipe of anywell-knownform of street oiler, oil or fluid being forced theretothrough the central pipe 11. At equal intervals between thetwo ends ofsaid pipe are positioned the nozzles 12, each of which is provided withan external conical recess 13 in its outer end. These nozzles 12 areprovided with external threads by'which they are secured in the wall ofthe pipe 10, each nozzle having a conical inner end 14 extending Aintothe interior of said pipe 10. The conical projection 14 at the inner endof the base of the -same diameter as that of the said body portion withthe periphery of which the edge of said base conforms and registers.From opposite points in the wall of said conical end 14 and above theinner wall of the pipe 10 extend the two holes or restricted passages 15communicating at their opposite ends with the conical recess 13. Theseholes 15 are in the same plane and their axes converge within the recess13 preferably in the center thereof. As the jets of oil o1' fluid forcedthrough the pipe 10l pass `through these holes 15 they converge in thecenter of the recess 13 and are broken into a fan` shaped sprayextending longitudinally of said pipe 10. The various nozzles l2 arepreferably spaced near enough together to permit the various fan shapedsprays to,

strike each other, thereby breaking `the oil into liner particles andmaking a continuous sheet of line oil extending the entire length of thepipe 10.

In order to have the sprays from the nozzles longitudinally of the pipe10 it is es- I sential that the nozzles 12 should be positioned in thepipe 10 so that the holes 15 are all at right angles to the axis of saidpipe. By this arrangement the fluid passing through each pair of saidholes 15 will impinge upon each other and be forced outwardly into a fanshaped spray at right angles to the path of said fluid as it isdischarged from said holes 15. It is self-evident, however, that asingle nozzle may be used to good advantage for some classes of work, inwhich case it might be threaded to the end of the delivery pipe, or inthe side wall as shown.

The holes 15 are located suiliciently above the inner wall of the pipe10 to permit the sediment to collect in said p ipe without clogging saidholes 15. Moreover, as the iiuid'is forced through the pipe 10 it willVstrike the conical end 14, thereby causing it to be moved over themouth-of the holes 15 thus keeping them free from sediment.

When in operation the oil or other iluid passing through the holes 15will be delivered to the ground with such force and in such a fine spraythat it will penetrate all the dust of the road and soak it thoroughlyrather than settle on top of the same, as is usually the case. Obviouslythis is a great improvement.

his nozzle is very effective in its opera.- tion and is simple inconstruction, as is evident from an inspection of the drawings.

drical body portion terminating at one end in avconical projection Witha base conforming to and registering with the periphery of said bodyportion, and provided at its opposite end With a conical recess With anunbroken Wall, said body portion having two diametrically disposedsteeply inclined passages extending from the inner end of said conicalrecess to the face of said conical projection at points above the basethereof.

2. A nozzle having a cylindrical body portion terminating in a coneshaped end the base of which is the same diameter as said body portionand provided with a conical recess at the opposite end, the Wall ofwhich is unbroken and more steeply inclined than the Wall of said coneshaped end, the face of thelatter having extending therefrom elongatedrestricted passages diametrically disposed parallel to opposed lines ofthe Wall of said recess With which the opposite ends of said passagescommunicate.

3. A. nozzle having an elongated cylindrical body portion terminating atone end in a conical projection With a base conforming to andregistering With the periphery of said body portion, and provided at itsopposite end Witha conical recess with an unbroken steeply inclinedWall, said body portion having two diametrically disposed steeplyinclined passages extending from the inner end ofsaid conical recess tothe face of said conical projection at points above the base thereof.
